If you want the locations of all the shelters try the AT Overlay for Google Earth.

Nicest we've seen in 825 AT miles: Quarry Gap Shelter in PA. Nice little fence and gate, daffodils blooming in the "yard", baskets of pansies hanging from the eaves. Very well taken care of!

[Re: Quarry Gap shelter]
Yes, the pride is apparent. Though the flower boxes are a bit much. But IMO it's a horribly inefficient design -- for the lumber involved, it should have a lot more usable room than it does. I found the setting claustrophobic and gloomy. I was there toward the end of a gray gloomy day though. Might be different in better weather, I dunno.
+1 on Quarry Gap. I met the Overseer and he really takes pride in the shelter. The bear box is another plus.
Thomas knob shelter by far is my fav.
Yeah, it's been asked before. Two stick out: Partnership in S VA when it was new b/c of the shower and that it hadn't been run down yet, and---the opposite---a really old dilapidated, even dry, one that's 1.5 mi. off the trail, in Harriman State Park in NY that leaks terribly in any long rain, West Mtn. Shelter, due to the superb views of (1) the Hudson River Valley and (2) on the horizon, Manhattan.
I just have to put in a plug for Upper Goose Pond Cabin. It's not a traditional AT type shelter but a fully inclosed cabin. It offers indoor sleeping for 16 hikers on bunks with materesses. It's located on a very nice pond with swimming and a canoe. It comes with a caretaker who provides springwater and a pancake breakfast. All for the cost of a donation, if you choose.
If you are a thru-hiker and don't stop at least for a visit, you are missing one of the great AT experiences.
